Conky on Ubuntu 64 Bit – .conkyrc

Posted by on Mar 9, 2008 in Conky, Programming, Technology, Ubuntu27 comments

Conky ScreenshotI recently installed Conky, which is a highly configurable and “light weight system monitor”. As with many packages, it’s available via the Ubuntu Repositories:

sudo apt-get install conky

The default installation outputs some pretty useful information about the system – CPU usage, RAM/Swap usage, HD IO, HDD space and so on, and there are also some awesome scripts available to pull in other information to the display. The data monitored by Conky is controlled by the .conkyrc file locate in the user Home directory ~/.conkyrc. Opening and editing, or creating this file if it doesn’t exist (Applications -> Accessories -> Text Editor then Save As .conkyrc in the home directory), .conkyrc allows full control of how Conky gathers and displays information. The first section of the file, controls how the physical aspects of Conky is handled – the window size, transparency, position on the desctop etc., and the second part of the file takes a number of variables – both built in to Conky (which gather information such as RAM usage, etc.), and via exec, execi and texeci commands.

The Conky website has a great references on the configuration settings, available variables, and the man page.

I’ve also recently written a post which deals specifically with setting up Dual Core processors – Conky: Dual Core Processors in .conkyrc

As previously mentioned, in addition to Conky’s built in variables, it is possible to execute external shell commands, and even Perl/Python etc. scripts, and have the output sent to Conky for processing. I currently have two scripts installed, both obtained from Ubuntu Forums:

Conky Gmail Revisited, written by lvleph, is a Perl script, which logs into your Gmail account, and checks for new mail periodically (the interval of which is actually controlled via the .conkyrc). The Perl script is easy to download and use. Once I saved the script to ~/ConkyScripts/gmail/gmail.pl I just had to modify the script to enter my Gmail username and password, and make it executable

cd ~/ConkyScripts/gmail/
sudo chmod a+x gmail.pl

I could then call the script from my .conkyrc:

You have ${texeci 360 perl ~/ConkyScripts/gmail/gmail.pl n} new gmail(s).

texeci is a Conky command, to which I passed the parameters 360 (an interval in seconds which the script should run), and the shell command to execute – in this case, perl ~/ConkyScripts/gmail/gmail.pl n (the n is actually a parameter passed to the gmail.pl script!). The original forum post has a great list of installation instructions, thanks to lvleph.

I also added

${execi 360 perl ~/ConkyScripts/gmail/gmail.pl s}

to .conkyrc which calls the script again, but with “s” as the parameter, to output any new email subjects to Conky.

Conky Weather Revisited V2, also written by lvleph, grabs local weather information. It even comes with its own Weather Font! Again, it’s easy to download and incorporate into the .conkyrc file (I recommend the version from Page 3 of the forum thread – just remember to download the font from the front page). Again, I saved this to its own directory ~/ConkyScripts/weather/weather.pl and it was just a matter of calling the script from the .conkyrc as before. Running

./weather.pl

in a terminal window outputs the possible parameters which can be passed to the script – the most important being the area code/city code – in my case THXX0027, for Mae Hongson. Again, the original forum post has a great list of installation instructions, thanks to lvleph.

I’ve also recently written a Perl script, which allows BOINC data to be viewed via Conky. See my recent post on BOINC and SETI@Home with Conky, on Ubuntu.

Desktop with Conky

So, here’s my full .conkyrc file, for anyone who’s interested, which outputs the image above – try and tested on an Acer Aspire 5052, with AMD Turion 64 X2 (Dual Core) Processor:

The “Post your .conkyrc files w/ screenshots” thread over at Ubuntu Forums has many other .conkyrc examples to peruse.
